In this yoga class, we don't hold poses, we "feel their hellish fire creeping into our bones." We don't rest in Savasana, we rest in peace in Corpse Pose. At Saskia Thode's Metal Yoga Bones, you're more likely to see jeans than spandex, leather than Lululemon. The generously inked German transplant, who brought her dark practice to the velvet-lined backroom of Bushwick's Cobra Club earlier this year, has created the ideal class for people who want to sidestep all the hippie-dippy bull and crank up the badass on their yoga. A standard Vinyasa flow is set to heavy metal: Judas Priest and Iron Maiden amp the room up, while Celtic Frost and various instrumental numbers help the intimate class wind down and offer themselves to darkness. But unholy communion with Satan is optional — Thode has said her intention is to create a light, fun, judgment-free class where the heaviest thing is the music. And that she does. Because sitting in Prayer Position is way more fun when it's called "hand horns." Rock on. 6 Wyckoff Avenue, Brooklyn 11237, 917-719-1138, metalyogabones.com

Tourists and newbies might be dazzled by the Disney-fied charms of the neighboring Brooklyn Bowl, but locals know that The Gutter is the place to bowl in Williamsburg. Brought to you by the masterminds behind the Barcade franchise, the Gutter offers a massive main bar area with a Plexiglas window that looks out onto eight lanes reclaimed from a 1970s-era Iowa alley. Games run $7, or $40 per hour — a two-for-one happy hour deal kicks in after 1 a.m. from Sunday through Thursday and on Friday from 2 till 6 p.m. — and shoe rentals are $3. Serious keglers can avail themselves of the Gutter's bowling leagues, while the more cerebrally inclined might match wits during one of the liveliest trivia nights around. The bar is snacks-only, but they'll let you order delivery from nearby restaurants. Waits can get a little crazy, but with ample booze and seating, it's definitely worth your while. If you want to bowl like you're a kid again, the Gutter is your best bet. Actual little Lebowskis should stay with a sitter, though — these lanes are 21+. 200 North 14th Street, Brooklyn 11211, 718-387-3585, thegutterbrooklyn.com

When the Hudson Hotel launched Putt Putt Park, a pop-up mini-golf course atop its courtyard, this past spring, the only complaint was why it wasn't a permanent installation. The nine-hole course, which included the obligatory windmill and loop-the-loop, was open all April, priced at $10 a round, plus golf-themed snacks and cocktails. All this with the façades of Columbus Circle looming overhead! Backyard-style string lighting allowed games to continue safely into the night. Given that it was one of a precious few mini-golf courses in Manhattan, it's hardly a surprise that the pop-up's expiration prompted a public outcry. The Hudson promised an extended return — in April 2016. If you missed the initial tee-time, note that there's a movement to reopen Putt Putt Park this autumn. So keep an ear to the green and keep your short game sharp. 356 West 58th Street, Manhattan 10019, 212-554-6000, morganshotelgroup.com

It's a schlep from the train, you generally have to wait for a court, and the only bathroom is a porta-potty. But the ten public courts in Riverside Park, painstakingly maintained by the nonprofit Riverside Clay Tennis Association, are worth the hassle. They sit on a glorious patch overlooking the Hudson River near 96th Street, with Jersey views to the west and pre-war apartment towers to the east. Best of all, the courts are ravishing red clay, a variety typically encountered in the private clubs of Europe, not the public parks of New York. The vibe is relaxed yet structured, avoiding both the rigidity you encounter at the Central Park Tennis Center and the chaos of many courts downtown and in Brooklyn, which often lack attendants. Weather permitting, the courts are open daily till dark, April through December. Reservations are welcomed and encouraged, and the RCTA also offers lessons and tennis clinics. Be sure to bring your city tennis permit (or $15 for the hour) and sweep the court when your time is up. West of the West Side Highway at 96th Street, Manhattan 10128, 212-978-0277, rcta.info

Pelham Bay Park feels nothing like most of New York City — and it almost isn't. The vast green space, three times the size of Central Park, inhabits the far northeast corner of the Bronx. For runners coming from other boroughs, the journey is rewarded with a stunning variety of nature to explore. Jog along the Long Island Sound shoreline from Orchard Beach or through wooded paths in the park's interior — or get on a riding trail for the chance to see some horses. There's good people-watching, too, thanks to basketball, bocce, and roller-hockey courts. As you exercise, consider the park's fascinating history: It was once home to Anne Hutchinson's dissident colony, which she formed after a dispute with Puritan leaders during the colonial period. Once you've worked up an appetite, head to nearby City Island for some seafood. Off Shore Road across the Pelham Bridge, Bronx 10464, 718-430-1891, nycgovparks.org

We're lucky to roll deep in bike paths and parks in New York City, but extended rides along uncongested greenways can be hard to come by. Your best bet is to head out to the Shore Park Greenway, a two-segment, twelve-mile span of south Brooklyn that offers views of the Statue of Liberty, the Verrazano-Narrows Bridge, Coney Island, the Manhattan skyline, and New York Harbor, plus lovely stretches through urban parks. Start at Owl's Head Park in Bay Ridge and hug the shoreline as you pedal around to Bensonhurst Park at Gravesend Bay. Pick up the trail again on the east side of Coney Island and head up toward the Canarsie Piers via the Brooklyn Marine Park to Spring Creek Park in Queens. There are plenty of places to picnic along the way, though you could also hop off the trail and head to a nearby restaurant or bar. It won't feel like it at times, but you are still in New York City, after all. nycgovparks.org/parks/shore-road-park
